Symptoms
- Visible fraying, exposed wire, or cracking near the connector or strain relief
- Charging only works when the cable is held or bent a certain way
- Cable feels stiff, kinked, or discolored near the ends
- Charging is intermittent despite a clean port
Likely causes
- CommonNormal wear from bending near the connectorsThe area right where the cable meets the connector flexes the most and wears out first.
- CommonWrapping the cable tightly for storageTight winding stresses the internal wires and jacket over time.
- PossiblePulling the cable by the wire instead of the connector to unplug itThis puts direct strain on the internal connections at the point of failure.
- PossiblePet chewing or accidental cuttingPhysical damage from outside sources can expose wiring quickly.
What to do
- Inspect the full length of the cable, especially near both ends, for cracks, fraying, or exposed wire.
- Stop using any cable with exposed metal wire visible, even if it still technically charges.
- Replace the cable rather than trying to tape or repair exposed wiring.
- When buying a replacement, choose an MFi-certified cable for reliability and safety.
- Store new cables loosely coiled rather than tightly wound to extend their lifespan.
- Unplug cables by gripping the connector, not pulling on the cord.
- Consider a cable with reinforced strain relief or a braided jacket if you tend to wear cables out quickly.
- Dispose of the damaged cable rather than keeping it as a backup, since the risk remains even for occasional use.

When to call a pro
This just needs a replacement cable; no professional service is needed unless the port itself was also damaged.
Safety
Use caution
Stop using any cable with exposed wiring, since it can cause a short or, in rare cases, a minor shock or spark.
